from: 2:3 Primary Inputs and Outputs
ÅThe special significance of primary input and output ports is that they are
connected automatically by the processor if no explicit binding is given.Ë
Is it valid to assume then that if an input port is not a primary port, it
is not automatically connected by the processor?
I ask because when I run this pipeline in Calabash 0.6.0:
<p:declare-step xmlns:p="http://www.w3.org/ns/xproc">
<p:input port="source">
<p:inline><foo>bar</foo></p:inline>
</p:input>
<p:output port="result"/>
<p:identity/>
</p:declare-step>
I get this output:
<foo xmlns:p="http://www.w3.org/ns/xproc">bar</foo>
This puzzles me, because identity has no primary ports:
<p:declare-step type="p:identity">
<p:input port="source" sequence="true"/>
<p:output port="result" sequence="true"/>
</p:declare-step>
I expected either no output or an error message.
Do I misunderstand primary ports? Or is Calabash automatically connecting
something it should not? Or am I overlooking something?
I appreciate any insight,
